Potential impact of chemical prophylaxis on the incidence of gonorrhoea.

How often are gonorrhoea and genital yeast infection sexually transmitted?

“…The figure for gonorrhoea resembles the figure of 66% for infected female contacts quoted by Barlow et al (1976) and is notably higher than the estimate given by Lee et al (1972). The figure for genital yeasts closely resembles the estimate of 39% reported by Thin et al (1977).…”

“…as assessed by Thin et al (1971), but at the same hospital Barlow et al (1976) indicated that it was only 66%. Furthermore, Lee et al (1972) suggested that infectivity of gonorrhoea was very much lower, between 5 and 407o with a mean of about 27%.…”

A theory of the epidemiology of gonorrhoea.

“…The continuity of both local and national trends is evidence against the existence of such a precarious situation. Lee et al (1972) devised a simple model which was based on the assumption that gonorrhoea had been increasing in the USA at an exponential rate. They reason that this means that there is a 'positive feedback loop' or that an increase now will lead to an even bigger increase later.…”

“…She, like Lee et al (1972), concludes that relatively small changes such as the reduction of the duration of infections in women from 100 to 92 days would halve the prevalence of gonorrhoea in about three years. If the reduction was maintained the prevalence would continue to fall.…”

Letter: Elimination of gonorrhoea.

“…Yours Elimination of gonorrhoea TO THE EDITOR British Journal of Venereal Diseases SIR-In their letters to the editor, Felton (1973) and Spencer (1973) gave some additional thoughts on the paper 'Potential impact of chemical prophylaxis on the incidence of gonorrhoea' by Lee, Utidjian, Singh, Carpenter, and Cutler (1972). Felton stated that 'the question of the acceptability of the intravaginal contraceptive compounds (ICC) vis a' vis other contraceptive and preventive measures is not discussed.…”
